HELP: Retargeting older UE4 Mannequin animations to work with MetaHuman in UE5.2

I’m trying to retarget older UE4 Mannequin animations that were originally created for use in UE4 to work in UE5.2 and Metahumans I was able to successfully to retarget newer UE4 Mannequin animation that are using the UE5 version of the UE4 Mannequinn no problem using the documentation.

What do I need to do differently to get these older UE4 Mannequin animations to work with Metahuman in UE5.2?
